我需要三个PHP函数来优化这段代码，加速，请帮助这个我用于PHP分类网站的所有功能，

品牌 - 如果有人进入品牌，则会提供更多细节

clean_url - 用于从URL中删除不需要的字符 clean_title - 用于清除Title中的不需要的字符，所有

    function brandwords( $in ) {
        $wordToFind =  array(
           'suzuki' => 'Suzuki' , 
           'Toyota' => 'Toyota',
           -------------------------------- big database. 
        );

        $words = preg_split('/\s+/', remove_numbers(strtolower(trim($in))));

        foreach ( $wordToFind  as $key => $value ) {
           if ( ( $pos = array_search( strtolower( $key ), $words ) ) !== FALSE ) {
               return $value;
